Damn fine work Alton!

as soon as i seen the weird ass name i read it backwards and BAM! lol Ill agree, give the guy credit-determined as fuck bro! At this point im just gonna give up and like the lil dude PS-Im at -11 rep last time i looked, so youre not alone good sir!

Reason number 45,213,876 to support SSA! Keep it up guys.

We expect a few vids of said awesomeness Mr. Clinton!

You sir just became the mod of all mods! love it

Why thank you. June 8th it will be even more. Do tell

Are you serious?? I thought the whole idea of car audio batteries was high ah ratings. Jeez I obviously need to quit or do years more research! *In no way shape form or fashion is this directed at you Julian, I just honestly had NO clue the ah rating wasn't the main factor in car audio smh

I was thinking this too. Are there any specific things I could check?

it stays in 13s MOST of the time but not always as I would like. yes, voltage at alt is 14.0 voltage at front battery 14.0 voltage at back battery 13.9 I have not measured them at full tilt but I will today. Thanks everyone, especially pm, for explaining im maxing my one run out, makes perfect sense. Edit-some songs DO take it down below 12v....

Just one run front to back. Never dreamed I would need more with no voltage drop...

Thanks pm, that's what I was looking for. The volt meter is hooked up to the rear battery that both amps are connected to. I have almost literally zero voltage drop from front to back so I know that's good.

The way i done mine was ground alt to battery which is grounded to frame

Its a 35a battery. pretty small. spv35 maybe?

Cant wait to see how it works out. keep us posted man.

Or will it always dip to low 12s without a 300+ amp alternator?

I guess i should have said i am definatly adding another platinum to rear I just wondered if voltage would stay in 13s theoretically

Ken, have you seen or heard any c pillar walls? I thought about it myself but have never seen or heard of them.

That is while driving so idled up I would say. Two Fosgate T1500bdcp ran at 2 ohm each and a Fosgate P800x4 on highs Yes my grounds are good and alternator is grounded.

I put my mechman 240a alt on and have a group 65 diehard platinum under hood and small stinger in back. when playing full tilt on heavy bass im seeing low 12s. If i add another big plat in the back will this keep my voltage in the 13s or will it still drop to 12s as that's what the batteries rest at? this may be stupid question but none the less i am curious.

^^Listen to this OP. As stated before, you need to change your box before blowing money on amps....will make a much bigger difference than just replacing amps.

Thanks all! question is answered. I will be ordering from monoprice or knu, depending on shipping time

Will do shizzon, thanks for your time

Thanks pm, does the shielding make any difference at all really?

Thanks guys. That's not TOO bad of a price on that knuconcepts wire. Shizzon is their wire ofc and of correct size?
